Dr. Darshan Shah said doing the small things consistently had the biggest impact on his personal health journey.Madeline Tolle for BIThis as-told-to essay is based on a conversation with Dr. Darshan Shah, the 53-year-old founder and CEO of longevity clinic Next Health, who's based in Malibu, California. It's been edited for length and clarity.I've been a physician for 30 years. For the first three quarters of my career, I did all sorts of surgeries, from trauma and emergency surgery, to general and reconstructive cancer surgery.I loved surgery, and I still miss being in the operating room, but I was totally burnt out. I was not happy. I did not want to go to work, and I thought, who wants to live this way?I switched into longevity medicine about 10 years ago. I made the transition because I was 50 pounds overweight, had high blood pressure, diabetes, metabolic syndrome, and an autoimmune disease.Business Insider's Power Hours series gives readers an inside look at how powerful leaders in business structure their workday. See more stories from the series here, or reach out to editor Lauryn Haas to share your daily routine.I learned the science of nutrition, exercise, sleep, and functional medicine, brought all of that to my life, and got off all my medications and diagnoses of chronic diseases.The experience made me realize that reversing chronic diseases is the kind of medicine that I want to practice. I started health optimization and longevity clinics to help people improve their lifestyle, optimize their hormones, and get them to think about how to prevent and reverse chronic disease.I always say the most important thing is to have a really good daily routine. It doesn't need to be any medications, injections, or anything fancy. I saw the biggest movement in my own personal health journey when I did the small things consistently.Dr. Shah said he goes outside first thing in the morning.Madeline TolleI wake up at 5 a.m.I start off my routine first thing in the morning because the whole world is asleep, and it's the only time I really have for myself.The critical thing is what I don't do when I wake up. I don't wake up with my phone anywhere near me. I charge my cell phone by the coffee machine when I sleep, which is at the opposite end of the house.That's a critical piece of my routine, because the phone deteriorates our mornings and stresses us out the minute we wake up. I don't look at my phone until 15 minutes after I've woken up.I go outsideI'm lucky to have a little puppy now, but even before I had a puppy, I would go outside. I think it's extremely important to go outside first thing in the morning. If the sun isn't up yet, I go back outside when it's up because sunlight exposure is so important.The physical act of taking your body outside is something that has been ingrained in our biology since caveman days. Going outside sets your circadian rhythm, decreases your stress levels, and improves your heart rate variability.I do a quick workoutMy morning routine is my sacred time. It goes until about 6:15 a.m.The physical piece of my morning routine involves a quick 10- to 15-minute workout that includes stretching and lifting weights. Even if I don't get to the gym for the rest of the day, at least I got my workout in first thing.Dr. Shah said he drinks a vitamin mix called IM8.Madeline Tolle for BIIt's so important to get quick wins. You can even start off with two minutes or five minutes a day. It doesn't matter. Once you get that quick win, it will build upon itself.After I do the workout, I grab a cup of coffee and take all my supplements. I put creatine in my coffee and drink a vitamin mix called IM8. I also take a couple of other supplements, including True Nitrogen, Urolithin A by Timeline, and a probiotic.I read for 20 minutesThe second part of my routine is learning something new. I read for 20 minutes. I'm usually reading two different…

Shiyao Tang says she spent 5 months planning her exit from her $390K job.Shiyao TangShiyao Tang quit her $390,000 job at DoorDash to build Soir Si, a silk womenswear brand.Tang says she spent 5 months planning her corporate exit and was scared to leave a stable job.While she experiences moments of self-doubt, Tang says the risk is worth it to pursue her dream.This as-told-to essay is based on a conversation with Shiyao Tang, a 34-year-old business owner based in New York City and Paris. It's been edited for length and clarity.I was on a very strong upward trajectory in my manager role at DoorDash when I quit in 2025. I was making $390,000 and felt that I still had room to grow, but when I was honest with myself, my heart wasn't in it.Leaving to start my own silk womenswear brand wasn't an instantaneous decision; it was a long-term calling inside of me. It took a lot of courage to quit and choose the unknown.I still constantly ask myself if I made a huge mistake. I think to myself, "How could I just leave a job that most people would dream of?" It was high-paying, the benefits were great, and there was room for learning. But I don't want to look back and think I climbed the wrong mountain.I enjoyed my tech job, but felt an inner tug toward entrepreneurshipIn 2022, I was hired as a strategy and operations manager on the homepage team at DoorDash. My job was challenging, and I got to wear a lot of hats. I also developed deep friendships with some truly talented people.However, I realized I missed the feeling of being close to the people I was building for.Earlier in my career, I had a small entrepreneurial chapter where I worked on a fashion wholesale startup. I built my own customers from the ground up and interacted with them every day.When I was 16, I moved from China to the US and later spent a year studying abroad in Paris. I've always lived between cultures and felt super energized by working with people from distinct backgrounds and creative disciplines. The more I thought about it, the more I realized I wanted my career to reflect that part of me, too.I spent about 5 months deciding what I wanted to do before I quit, and the idea scared meTech created a structure for me to learn and expand my horizon, but I was ready to try entrepreneurship again. I spent a lot of time journaling and reflecting on what business I really wanted to make.Every weekend was dedicated to foundational discovery work and even talking to potential customers or friends to get some early feedback on different ideas. I even started connecting with other young, inspiring entrepreneurs at founder events, which expanded my horizons regarding what life might look like as an entrepreneur.Frankly, I was extremely scared every day, but seeing people thrive gave me more confidence to envision what it might look like for me. I decided on my business, Soir Si, where I make simple, minimal sculptural silk pieces. The mission is to make luxury accessible.Even though I was sure of my decision, walking away was scary, and honestly, it was really sad for me. However, the thought of not pushing to the edge of my potential was scarier than quitting.I now split my time between NYC and ParisI have my own apartment in NYC, and I spend half my time in Paris, typically staying with friends or family, to fuel my creative inspiration during the design process.The first month after quitting, I focused on building a strong visual and emotional identity for Soir Si by enrolling in online courses and even partnering with a freelancer. The next stages were developing my website, connecting directly with customers, and using my branding and website to open up my supply chain.Now I'm focused on securing and strengthening those relationships while sprinting toward product development.I still question whether I made the wrong decisionRight after quitting, I was so focused on transitioning into entrepreneurship that I didn't have time for…

Consumers are spending more than ever on mobile apps.Anusak Laowilas/NurPhoto via Getty ImagesThe "year of mobile" may finally be upon us.Mobile adtech firm Liftoff filed to go public this week.Industry experts predict other mobile ad firms will follow, ending an adtech IPO drought.Could the adtech IPO drought be coming to an end?This week, Blackstone-backed mobile adtech firm Liftoff filed to go public in the US, potentially ending a yearslong freeze that has seen only one major pure-play adtech IPO — connected-TV firm MNTN's debut last spring — since 2021.If the IPO market does reopen in earnest this year, adtech executives expect the first movers to resemble Liftoff. That means companies with consistent growth and exposure to performance advertising, the slice of the market focused on measurable outcomes like app installs and online sales, which is increasingly powered by AI.Liftoff provides a software development kit that app developers install in their apps in order to sell advertising, and a product for advertisers that uses machine learning to help them target high-quality mobile users. It grew revenue by 30% year over year to $491 million in the nine months that ended September 30. The company reported $263.3 million in adjusted earnings — a 54% margin — and a net loss of $25.6 million in that period.The mobile adtech companies InMobi and Moloco have similar profiles and could be the next candidates in the space to go public, industry experts said. The mobile adtech space has consolidated into just a handful of big players in recent years, including AppLovin, gaming engine Unity's mobile ad business, Google's AdMob, and Hong Kong-based Mobvista. Fresh IPO money could spark more M&A.SoftBank-backed InMobi has long been rumored as an IPO candidate. Bloomberg reported in July that the company was aiming to raise as much as $1 billion in an Indian public listing at a valuation of between $5 billion and $6 billion, citing people familiar with the matter. Business Insider was unable to verify InMobi's IPO plans. InMobi declined to comment for this article.Ahn Ikjin, CEO of Tiger Global-backed Moloco, said in an interview with a Korean news outlet last month that "going public is one of the milestones that we aim to reach," but didn't specify a timeline. Moloco declined to comment.Here's why the market looks ripe for a year of mobile adtech IPOs.The AppLovin effectAppLovin's meteoric rise has pushed its market cap past $200 billion, cementing its status as the most valuable pure-play adtech company by a wide margin. The company has some of the highest profit margins in all of tech — not just adtech — powered by its AI-driven Axon targeting platform and a recent expansion beyond gaming into e-commerce advertising.Other mobile adtech companies and their investors will be hoping some of AppLovin's magic rubs off on them."AppLovin is a bellwether for a buoyant space," said Ciaran O'Kane, general partner at the adtech-focused venture fund FirstPartyCapital.'Performance' pays on mobileHow did placing ads in solitaire games and talking cat apps become such a money-maker?Consumer spending on mobile apps was estimated to have grown 21.6% year over year to reach $155.8 billion in 2025, according to the app intelligence company Appfigures.App advertisers are "typically more focused on math than art," said Alex Merutka, CEO of the creative technology platform Craftsman+.They're laser-focused on making tiny tweaks to variables in targeting, ad creative, and whether you show an ad in the first 30 seconds of the game —or the first 45 seconds — in order to drive performance. These advertisers are willing to pay top dollar to target potential "whales," the users who are most likely to spend big once they download an app.Mobile adtech companies have transformed from middlemen that simply placed ads on…
